Product Overview

AD5122A is a dual channel, 128-position, I²C, non-volatile digital potentiometer. The low resistor tolerance and low nominal temperature coefficient simplify open-loop applications as well as applications requiring tolerance matching. The linear gain setting mode allows independent programming of the resistance between the digital potentiometer terminals, through RAW and RWB the string resistors, allowing very accurate resistor matching. The high bandwidth and low total harmonic distortion (THD) ensure optimal performance for ac signals, making it suitable for filter design. The low wiper resistance of only 40 ohm at the ends of the resistor array allows for pin-to-pin connection. It is used in applications such as portable electronics level adjustment, LCD panel brightness and contrast controls, programmable filters, delays, and time constants, programmable power supplies.
  • Resistor tolerance is 8% maximum at (VDD = 2.3V to 5.5V, VSS = 0V)
  • Low temperature coefficient is 35ppm/°C typical at (VDD = 2.3V to 5.5V, VSS = 0V)
  • Bandwidth is 0.43MHz typical at (RAB = 100Kohm, VDD = 2.3V to 5.5V, VSS = 0V)
  • Fast start-up time is 75µs maximum at (VDD = 2.3V to 5.5V, VSS = 0V)
  • Linear gain setting mode, single- and dual-supply operation
  • Independent logic supply range from 1.8V to 5.5V
  • Resistor noise density is 20nV/√Hz typical at (RAB = 100Kohm, VDD = 2.3V to 5.5V, VSS = 0V)
  • VW settling time is 12µs typical at (RAB = 100Kohm, VDD = 2.3V to 5.5V, VSS = 0V)
  • Operating temperature is -40°C to +125°C, resistance is 100Kohm
  • Package style is 16-lead LFCSP
